Endometriosis effects 2-5 % of women at reproductive age. Malignant transformation of endometrioma is around 2.5 %. Ovarian mucinous tumors constitute approximately 10 % of all ovarian neoplasms. A 35-year-old woman with gravida 0 parite 0, admitted with pelvic pain for two days, to our hospital.She had laparoscopic surgery for right ovarian cyst nine years ago, the pathological examination of which was endometrioma. Gynecological examination of patient revealed semisolid masses about 6 cm in diameter in bilateral ovaries. CA-125 and CA-19,9 were found 121.5mIU/L, 127.3mIU/L, respectively other tumor markers were within normal levels. After her approval bilateral ovarian cyst excision with laparotomy was carried out. Pathological examination demonstrated mucinous cystadenoma in the right ovary and endometrioma in the left ovary. Ovarian ephitelial malign tumors can be found together with endometrioma. Epithelial metaplastic transformation, especially ciliated cell and eosinophilic transformation were often reported, whereas hobnail and mucinous transformation were reported rarely in ovarian endometriosis. Mucinous metaplasia and hyperplasia in ovarian endometriosis might be closely associated with the development of mucinous borderline tumors. We didn’t find mucinous cystadenoma reported together with endometrioma in literature.
